I like using loops

Usually to add something I hadn't thought off... some weird stereo rhythmic effect, or a texture. Plus you can always bend a loop, chop it up, pile on FX and mould it to your will. Not like you have to have it sitting on its own, being flagrantly not yours.

Plus I only know how to make a limited number of noises, and have limited production ability so its nice to use other people's efforts to make my own work sound better.

i also get bored quickly, and if I didn't have loops to play about with I think I'd just give up on stuff through lack of interest. Sometimes I make something and just get a nagging sense of something being missing, then I cycle through a zillion percussion loops and find something that perfectly complements - like the missing piece I didn't realise I was missing.

Also good for when you run out of inspiration, and need a helping hand.

So thumbs up for me.
